Abstract: A sealed gas surface burner having a ring portion that sits on the main top around the periphery of the main top aperture through which the burner extends. The ring portion forms a substantially liquid tight seal with the main top, and has a raised shoulder to prevent liquid on the main top from running down through the burner aperture in the main top. A burner body is supported by the ring portion at spaced intervals to provide passageways from underneath the main top. A cap is supported by the burner body thereby forming a chamber which receives a mixture of gaseous fuel and primary combustion air. The mixture issues from ports in the side wall of the burner body where it is ignited to produce a cooking flame. Secondary combustion air is drawn from underneath the main top through the passageways in the burner to support combustion of the flame.

Abstract: A gas surface range having a downdraft ventilation system with automatic shut off during ignition. A relay is activated by current flowing to the spark coil of the electrical igniter, and has contacts connected in series with the blower motor of the downdraft system. Thus, the downdraft system is disabled during attempted ignition, and is automatically enabled at the completion of ignition.
